Hi,
I just got started with BOINC and set it up on three computers. Turns out, one of them doesn't have enough horsepower for the tasks. The completion time just keeps getting longer and longer. I tried tweaking settings on that PC, but after a 3 days decided it just wouldn't cut it. So I've removed BOINC from that PC. It had one task in progress with a deadline of Sept 1. Obviously that task will never complete. So I guess it will expire. But if you want to save time, you can assign it to someone else.

Why does the "to completion time" go up?
well, it was running for 3
)
well, it was running for 3 days, on one task
it started out as say an 8 hour job
after four hours, it said it needed 10 more hours
the next day it said it needed 20 more hours
the ext day it said it needed 40 more hours
or something like that
the CPU benchmark had really low numbers
other projects had the same problem, so I concluded that PC doesn't have enough MIPS/memory/whatever to support BOINC. It might be Norton 360 bogging it down, or the Pentium M processors throttling back, or who knows what. I played around with the advanced view prefs etc.
I'm running BOINC and e@h on another PC and iMac and getting work done.
Hi Michael, I don't know

Hi Michael,
I don't know how it is in Windows.
But BOINC tasks run with the lowest priority. This means that although they are running, power saving kicks in and reduces the clock speed of the processor. My Pentium M laptop 1.8 GHz goes down to 800 MHz, AFAIK. You have to explicitely deactivate that feature.
Some crude math: A "Global Correlations" task takes approx. 12h on my AMD 9350e, so maybe 24h on your laptop at full speed. Assuming that clock frequency goes down 50% we are at roughly 2 days to completion. And you not even used your computer for other things. Playing games, doing video converting or sth. like that would use the whole processor.
Just my 2 cents,
Michael
